Lifter sprites

Lifter sprites live under rocks, so go into the tunnels and woods and tap every rock.
Lifter sprites can be found in the woods, i don't know the exact locations though. You can
find one thicket sprite in the sod maze though. Once you get more go back through every
section of the map to see if you can get to new sections of the map, this way you can
progress more and find more sprites
